FIREARM.

Specification of Letters Patent.

Patented June 18, 1912.

Application filed June 25, 1909. Serial No. 504,327.

To all whom it may concern:

Be it known that I, ALFRED H. WORREST, of Lancaster, in the county of Lancaster and State of. Pennsylvania, have invented certain new and useful Improvements in Firearms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fire arms and more particularly to improvements in double-barrel guns,one object of the invention being to provide simple and efiicient means whereby an ordinary double barrel gun employing double trigger and firing means can be converted into a single trigger double barrel gun.

A further object is to provide a single trigger mechanism for a double barrel gun, which shall be complete within itself and capable of being inserted bodily into the gun, so as to operate the scars and not dependent for its operation, upon any other part of the gun mechanism.

A further object is-to so construct a selfcontained single trigger mechanism for a double barrel gun, that it can be readily applied to the trigger plate of the gun and supply a proper finish for the latter.

A further object is to provide a single trigger mechanism employing a recoil locking bolt, in which the firing means will normally lock the recoil bolt and in which the firing means may be locked so as to prevent the operation of the same.

With these objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation showing my improved, selfcontained, single trigger mechanism; Fig. 2 is a sectional view showing the location of my improvements in a gun; Fig. 3 is a detail view, partly in section showing a portion of the mechanism, Fig. 4 is an end view of the recoil bolt, and Fig. 5 is a view of a portion of the trigger plate.

1 represents the lock casing of a gun, with which the barrels 2 are. connected, said casing 1 containing any approved construction of inclosed hammers, cooked by breaking the gun and released by sears which project rearwardly from said casing. In

Fig. 2 of the drawing, the tang is represented at 4, and 5 indicates the trigger plate.

In an ordinary double barrel gun employing two triggers, the trigger plate is provided with two slots 6, 6, for the accommodation of these triggers. In order to convert such a gun into a double barrel, single trigger gun, the trigger plate will be cut as indicated by dotted lines in Fig. 5 to form a single centrally located slot 6 for the accommodation of my improved self contained, single trigger mechanism. In constructing this mechanism, I employ a rectangular frame 7, the lower member 8 of which is adapted to enter and close the elongated slot in the trigger plate so that its lower face will lie flush with the lower face of said trigger plate. The lower portion of the frame 7 is provided at respective ends with lugs 9 which rest upon the trigger plate and are secured thereto. The frame 7 may also be provided with upwardly projecting arms 10-11 secured at their upper ends to tang 4. The frame 7 carries all the mechanism necessary to control the operation of the scars of the gun, and can be inserted bodily into position in the gun without removing or disturbing the sears which may already be in position, and thus this mechanism is self-contained.

The lower member 8 of the frame 7 is provided with a slot 12 for the accommodation of the trigger 13, the latter being pivotally supported near one end by a pin 14 passing through a slot 15 in one end of the frame 7. The trigger is made with a toe 15 engaged by a spring 16 secured to one of the lugs 9 for maintaining the trigger normally in and returning it to its normal position. The pin 14 also pivotally supports two links 17 each having a pin 18 disposed under one of the sears 8. Trip arms or levers 19 are pivotally attached at their lower ends to the links 17 and the movements of these arms or levers may be guided by a slotted plate 20 secured to the top member 21 of the frame 7 by means of a screw 22. The trip arms 19 are provided at their lower ends with toes 23 to engage screws 24 in the bottom member 8 of frame 7 and the upper ends of said trip arms are provided with fingers 25. Standards 26 rise from the top member 21 of frame 7 and between these standards, two tumblers 27 are mounted and connected so as to be movable together.

The finger 25 of one trip arm is disposed in line with one of these tumblers and the finger 25 of the other trip arm is located in the path of the other tumbler, so that when said tumblers are turned in one direction or the other, one or the other of the trip arms will be moved out of the path of a plunger 28, connected with the trigger 13.

The plunger 28 passes upwardly through a slot 29 in the top member 21 of the frame 7 and is guided by a pin 30 passing through a slot 31 in said plunger. IVhen the trigger is pulled, the plunger 28 will be raised and,

' engaging the finger 25 which may be disposed over it, will raise the trip arm from which the finger projects and consequently raise the link 17 which carries said trip arm, thereby operating one of the sears 3 to fire one barrel of the gun. It is evident that if the tumblers be shifted in the reverse direction, the other trip arm will be operated when the trigger is pulled, and hence the other barrel will be fired.

In order to retain the tumblers in the position to which they may be moved, a spring plate 32 is secured to the frame 7 and provided with recesses 33 to be engaged by a pin 34 which projects from one of the connected tumblers 27.

It is desirable to provide means for locking the firing mechanism in order to prevent accidental firing of the gun when the latter is being handled more or less roughly and carelessly, and for this purpose the devices now to be described will be employed.

The top members 21 of the frame 7 is provided, at or near respective ends of the slot 29, with posts 30-31, through which a bar 34 is horizontally movable, said bar being provided, between its ends, with an elevated portion 35 whereby a recess 36 is formed. The bar 34 is provided at or near one end wit-h a pin 37 which enters an elongated slot 38 at the lower end of a shank 39. The shank 39 depends from a slide 40 on the tang and passes through an elongated slot 41 in the latter. By moving the slide 40 in one direction, the bar 34 will be moved to such position that the recess 36 formed by the elevated portion 35 will be directly over a finger 42 projecting upwardly from the plunger 28, so that said plunger will be permitted to move upwardly and permit the operation of the firing mechanism. When the slide is moved in the reverse direction, the portion 43 of the bar 34 will become disposed over the finger 42 and prevent the V plunger from being raised sufiiciently to fire the gun,the bar 34 thus acting to lock the firing means. When the slide is in this posit-ion a suitable designation, such as the letter S denoting safety, will appear through the hole 44 in said slide. In order to retain the locking bar 34 in the position to which it may be moved, a spring-pressed pin 45, disposed in the post 30 will engage in one or another of two notches 46 in said bar 34. If desired, a notched spring 47 mayalso be employed and made to engage a pin 48 on the shank 39 to hold the locking bar 34 in place. 1

An indicator 49 may be provided to denote which barrel is'to be fired, and this indicator is operated by a pin 50 carried by 'the tumblers 27.

A recoil bolt 51 is located within the frame 7 and provided with a slot 52 through which the plunger 28 passes. This bolt is provided at one end with a weight or head 53 having a recess 54 therein. A pin 55 passes through one end of the frame 7 and the head 53 on the recoil bolt 51 and is provided at its free end wit-h a nut 56 having wings 57 to enter recesses 58 in the head 53. Between this nut and the rear end of the recess 54, a coil spring 59 is located. With this construction, when one barrel has been fired, the recoil will cause the shoulder 60 at one end of the slot 52 of the bolt 51 to engage the shoulder 61 on the plunger 28 and momentarily prevent the descent of said plunger, thus preventing the firing of the other barrel by an involuntary pulling of the trigger by the operator when the first barrel was fired and thus the firin mechanism will be momentarily locked by the recoil bolt. In view of the fact that the plunger 28 (which constitutes part of the firing mechanism) passes through the recoil bolt, the latter will be normally locked by the firing mechanism, thus securing said bolt against any displacement by the handling or bumping of the gun. Thus locking the recoil bolt insures against any misfires when the user desires to fire hurriedly.

It will be observed that the mechanism carried by the frame 7 is a single trigger alternating mechanism which is complete in itself and not dependent for its operation upon any part in the gun and not carried by said frame.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth.
